acpi: Reduce wait interval in delay loop for sleep
The optimization of sleep time in acpi code includes reducing the sleep
duration and increasing the polling frequency within the acpi _ON/_OFF
method. StorageD3Enable is activated in Google/Rex, and this
optimization results in a saving of approximately 25ms in D3cold resume
time, reducing it from around 160ms to 135ms.
BUG=b:296206467
BRANCH=firmware-rex-15709.B
TEST=boot test verified on google/rex
verified _ON/_OFF Method in SSDT.
